This review examines the current state of algal biodiesel production, addressing key challenges such as strain selection, high production costs, and environmental impact, and proposing solutions to guide future research in renewable energy. The production process typically involves open raceway ponds or closed photo-bioreactors, followed by harvesting, drying, and lipid extraction, with innovative methods like ultra-sonication in situ synthesis offering high-quality biodiesel. The review clarifies the roles of catalysts in the transesterification process and fatty acid methyl esterase (FAME) generation and stress-induced production, as well as the distinction between direct and indirect transesterification methods. The heterogeneous catalysts in transesterification have improved the purity of biodiesel and decreased processing times, while genetic modifications and nanotechnology-like innovative methodology have increased lipid production. According to economic estimates, high production costs remain a hurdle if the worldwide algae biofuel industry is estimated to be worth USD 8.38 billion in 2022. However, the financial viability may be enhanced by the co-production of value-added products (VAPs), projected to reach USD 53.43 billion by 2026. Despite significant advancements in the field, this paper showed the widespread adoption of algal biodiesel as a sustainable energy source using genetic engineering, coagulation-flocculation, synthetic biology, and biorefinery-based production to overcome technological and economic constraints focused on the last.

It is crucial to have an efficient method or technology for managing the system’s economics, security, reliability, environmental damage, and the uncertainties that come with fluctuating loads. In this context, this paper utilizes a framework based on probabilistic simulation of a demand-side management approach and computational intelligence to calculate the optimal value of saving utility cost (SUC). Unlike traditional methods that dispatch peak-clipped resource blocks sequentially, a modified artificial bee colony (MABC) algorithm is employed. The SUC is then reported through a sequential valley-filling procedure. Consequently, the SUC is derived from the overall profitability of the generation system and includes savings in energy costs, capacity costs, and expected cycle costs. Further investigation to obtain the optimal value of SUC was conducted by comparing the SUC determined directly and indirectly, explicitly referring to the peak clipping energy of thermal units (PCETU). The comparisons utilized the MABC algorithm and a standard artificial bee colony, and the results were verified using the modified IEEE RTS-79 with varying peak load demands. The findings illustrate that the proposed method demonstrated robustness in determining the global optimal values of SUC increments, achieving increases of 7.26 % for 2850 MW and 5 % for 3000 MW, compared to indirect estimation based on PCETU. Moreover, SUC increments of 18.13 % and 25.47 % were also achieved over the conventional method.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"75 ","pages":"Article 104258"},"PeriodicalIF":7.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the maximum job creation value is negative, suggesting that biomass co-firing technology is not an effective choice for achieving a just transition during the large-scale coal phase-out process, and it is less competitive compared to renewable energy. Additionally, we find that generation efficiency is linearly negatively correlated with the blend rate. Moreover, carbon emission intensity and job intensity are positively correlated linearly, while there is a nonlinear negative correlation between job intensity and the blend ratio.
